Tidal energy will become much more important in the future renewable energy mix. In the Netherlands several tidal energy pilots are present. One of these locations is the Eastern Scheldt storm surge barrier, which provides a unique location where tidal velocities are locally enhanced due to the presence of the barrier. Five turbines were installed in one of the openings of the barrier in 2015 by Tocardo. The construction of the storm surge barrier has led to sand hunger within the basin and erosion of the tidal flats. The tidal flats are important for coastal protection, local ecology, recreation, shipping and fishery. Implementation of more turbines is expected to lead to an additional deterioration in tidal flat area, which is undesirable. The research questions which have been formulated are: Which hypotheses can be formulated regarding - What are the governing processes of tidal flat development since the construction of the storm surge barrier?
- What is the influence of tidal energy extraction on the
governing processes in - governing processes in tidal flat development
based on scientific knowledge- ?
- How can modeling tools be
applied to - applied to accurately represent the influence of tidal energy extraction on the hydrodynamics
and morphodynamic processes to verify these hypotheses- and morphodynamic processes?
- How are the hydrodynamics affected with increasing tidal energy extraction and different positioning of tidal turbine arrays?
- How are the sediment dynamics affected with increasing tidal energy extraction and different positioning of tidal turbine arrays?
Which configurations of tidal turbine arrays tidal energy extraction scenarios can be implemented such that their combined effects remain below the threshold of acceptable erosion rates?
